Musicians Jam from long distances. Sound Familiar?

I heard this story on Npr while driving to work this morning.  The story features a site called Jamglue.com where you can colaborate with people over the net to compose music.  I think its geared toward people who play instruments.  I almost thought they were going to mention the Tracking scene but I was disappointed on that note.  It's Funny that this new site is getting all the publicity seeing that Tracking sites such ashornet.org used to host the same thing  Modarchive.org and Buzzmusic.de does this very type of Jam collaboration.  WE just call it a remix.
